The sun shade according to this invention com-' prises a horizontal top frame 10 for attachment above a window 11. The frame 10 is shown to comprise a strip of material having a front portion, side portions and end portions 12 in intite contact with the face of the building. The manner of attaching the frame in place comprises a clamp or keeper 13 extended over each of the end portions 12 and secured by screws or 300 the like upon the building wall. A pair of support rods 14 are mounted upon the frame 12 and are arranged at right angles to the window 11. Each of these support rods engages through the front side of the frame is and the rear portions 12.

A lazy tong structure 15 is provided on each of the support rods 14 and have their upper ends slidably supported upon the support rods in a er so that the lazy tong structure depends lit comprises a shaft 33 rotatively engaged through screws 21.

at the side of the window. More particularly each of the upper ends of the arms of each lazy tong structure is attached pivotally upon a slide member 16 which slidably engages on the support rods 14. A resilient means or other arrangement is provided for normally urging the upper ends of each of the lazy tongs away from each other so as to cause retraction of the lazy tong structure. This means comprises a stiff spring 17 for each of the lazy tong structures supported by a bolt 18 upon the frame 10' and having its ends formed with cutouts 19 so as to partially surround the rods 14 and so as to engage against the inner sides of the slides 16.

Brackets 20 are attached upon the frame 10 and 'rotatively support a pair of vertical screws 21- to the outer sides of the lazy tong structures 15 and a horizontal shaft 22 above the lazy tong structures. Each of these brackets comprises merely a strip of material having a vertical bottom end attached upon the sides of the frame 10, having horizontalintermediate portions through which the upper ends of the screws 21 engage, and having vertical upward directed inner ends from which the'ends of the shaft 22 engage. A means is provided for connecting the shaft 22 and the screws 21 for unitary rotation and comprises bevel gears 23- arranged respectively upon the ends of the shaft 22 and the upper ends of the screws 21.

Elements 24 are attached at their upper ends upon the frame 10 and shield the screws 21 and have their lower ends connected with plugs 25 threadedly engaging in elbows 26. Each of the elements 24 comprises a channel member. These members are arranged opposite to each other so that their arms are directed toward each other and so partially encase the screws 21. Braces 27 connect intermediate the ends of the channel members 24 and are arranged upon the window frame 11 or the wall of the building so as to aid in supporting the sun shade. The lower ends of the channels 24 may be sweated or in any other manner attached upon the plugs 25. The plugs 25 engage in the upper ends of the elbows 26 and the elbows are arranged to have their ends directed at right angles towards the wall of the building; Tubular elements connect with the latter mentioned ends of the elbows 26 and extend into the interior of the building. These tubular elements comprise a tubular element 28 for each of the elbows 26 connected with a plug 29 threadedly engaged into the ends of the elbow 26. The element 28 is provided with a flange 30 engaged against the outside of the wall. The end of the tubular element 28 partially extends through the wall and threadedly connects with another tubular element 31 which is extended in from the inside of the wall, and is provided with a flange 32 engaging the inner face of the wall. The flanges 31 and 32 serve to clamp against the wall and so aid in maintaining the sun shade in place.

A means is provided for rotating the screws 21 selectively from the interior of the building and each of the tubular elements 20 and equipped with bevel gears at the inner ends meshing with similar bevel gears upon the bottom ends of the ceive the ends of the turning tool 36 by which the device may be operated. The tubular ele-. ment 31 is'shown with internal projections 37 adapted to partially shield the extended end of The inner ends of the shafts 33 are equipped with square portions 35 adapted to remenace the shaft 33 to prevent any possibility of manual turning of the shaft by children or others not equipped with the proper turning tool.

A hood is provided for covering the portion of the sun shade, and in fact housing all of the sun ray frames when in their raised positions. The hood comprises a hollow sheet metal or similar element 38 attached upon the building and having closed ends, a closed front and a closed top, and an open bottom through which the sun shade extends. The front of the hood 28 is formed with a plurality of pressed out portions 39 forming passages therebetween for the air. The passages act as ventilators. The hood terminates .at the upper edge of the window 10 so as not to obstruct ventilation through the window.

Each of thelazy tongs 15 have pegs 40 projecting from various elevations therefrom and engaging in slides 41 freely slidable upon the screws 21 so as to support the lazy tong structures during their motion. The lowermost of these slides indicated by the reference numeral 41' is threadedly engaged with the screw. The arrangement is such that when either of the screws 21 is caused to rotate the slide 41 will lift or lower, depending upon the' direction of rotation of the screws 21, the lower-end of the lazy tong and so contract or expand the lazy tong structure. The lazy tong structure is composed of elements pivotally mounted intermediate by headed pegs 42 and pivotally connected with adjacent elements also by headed pegs 42. These headed pegs have shanks 43, an arrangement necessary for the detachably mounting of sun ray frames.

A detail of one of the sun ray frames is illustrated in Figs. 11-14 inclusive. Sun ray frames comprise side elements 44 of channel shape connecting with top and bottom elements 45 also of channel shape. The top and bottom elements 45 hold strips of felt 46 extending substantially their entire lengths and support a sheet of transparent material 47 of scientific determination so as to allow beneficial rays of the sun to pass through and restrain others. The material 4'7 itself forms no part of this invention since such materials are generally known and for this reason further description thereof will not be given. Each of the ends of the sun ray frames, that is the channel shape members 44 have openings by which they may be mounted upon the pegs 42 of the lazy tong structures.

More particularly each of the channel shaped members 44, have a slot 44 extended in from one side and located adjacentone end and communicating with a side opening 44 which latter opening allows the passage of the head of a peg 42 in a manner so that once the head passes, the shank portion, that is, the portion 43 extends through the opening 44. The opening 44 is arranged upon the side of the channel shaped member 44 which is opposite the entrance of openings 48 and 49. The opening 48 is more similar to the opening 44 except for the fact i nel. One of the ends of the strip 52 is adapted 0 to engage over the opening 44 to prevent the shank portion 43 of the peg from coming out once engaged. The other end of the strip 52 extends to the other side of the channel member 44 and is adapted to engage over the opening 51 to hold the peg within the opening 49. The slide 52 is so arranged that when one of the openings, for example, the opening 44 isunrestricted, then the other end of the strip engages over the mouth of the opening 49.

Each of the sun ray frames are adapted to be engaged across one of the elements of each of the lazy tong structures. Examining Fig. 2 it will benoticed that certain of the elements of the lazy tong structures have three pegs 42, one at the center and one at each end. The frame may be connected so that by first moving the handle 53 in one direction the mouth of the center opening 49 is unrestricted. The frame may then be simultaneously slid at both ends upon the central pegs 42 of a pair of elements of the lazy tong structure. ,The frames may be moved with the shanks 43 of the pegs at the base of the openings 49. Then ends of these lazy tong elements simultaneously pass through the openings 50. Next the latch must be moved into its operative position by moving the handle 53 so that the ends of the strips 52 close the entrance of the openings 44. The frames are now detachably mounted in place. The sun ray frames should be arranged so as to slope in the same direction and arranged so that when the lazy tongs are completely retracted all of the sun ray frames are substantially horizontal and adjacent each other. Furthermore when the lazy tongs are completely extended all of the sun ray frames slidably overlap when viewing from the horizontal.

The operation of the device consists in engaging the turning tool 36 upon one or the other of the shafts 33 for rotating and screws 21. Rotations from the screws will cause the elements 41" to move upwards or downwards depending merely upon the direction of rotation. As the frame elements move they will correspondingly collapse or extend the lazy tong structures and so the sun ray frames will be moved together or apart as desired. When the sun shade is completely collapsed all of the sun ray frames will be disposed substantially horizontal within the hood 38. A desirable position for the sun shade will be one in which all of the sun ray frames are arranged at an inclination to the vertical to allow the passage of the air and at the same side elements 44' of the frame support nontransparent metallic material 47' which is bent at a longitudinal edge 4'7 to form a protecting edge, for its lower adjacent sun ray frame. In other respects this arrangement is-similar to the preferred form of the invention and corresponding numerals may be recognized for corresponding parts. a
